An improved preconditioned conjugate gradient squared (PCGS) algorithm has recently been proposed, and it performs much better than the conventional PCGS algorithm. In this paper, the improved PCGS algorithm is verified as a coordinative to the left-

In this paper, improved algorithms are proposed for preconditioned bi-Lanczos-type methods with residual norm minimization for the stable solution of systems of linear equations. In particular, preconditioned algorithms pertaining to the bi-conjugate

We experimentally verify the effectiveness of metasurface reflectors in expanding 5G coverage into non-line-of sight (NLoS) regions in the 28-GHz frequency band. In outdoor open space measurements, the measured beam shape is well matched with that de
